A 16-year-old boy driving a Toyota Prius was waiting to merge onto the highway from Hammond Street when he was struck from behind by a Honda operated by a 17-year-old girl, Maine State Police Trooper Darren Vittum said.

The trooper did not release the name of either driver.

Vittum believes the Honda’s driver was looking over her shoulder at traffic and didn’t see the Prius in front of her. No one other than the driver was in the Honda, while the Prius had three teenage passengers in addition to the driver.

Both drivers were heading to Bangor High School when the accident happened shortly before 8 a.m., the trooper said.

The driver of the Prius suffered minor cuts and bruises and was treated at Eastern Maine Medical Center and then released, Vittum said. The Honda’s driver was not injured.

Both vehicles were totaled in the crash and traffic was slowed to one lane for about an hour, Vittum said.

“It created a little bit of a backup in traffic,” the trooper said.

Vittum urges drivers to use caution on busy onramps.

“Too many people are looking over their shoulder at traffic instead of the vehicle that’s right in front of them,” he said.
